Forensic anthropologist Temperance Brennan is caught in the middle of an outlaw biker gang-war in Deadly Decisions, the fourth book in Reich’s series of mysteries. While investigating the deaths of both bikers and innocents caught in their crossfire, Tempe finds a connection to a North Carolina teenager’s death in 1984. In the midst of her investigation she also has to deal with three very different men: a sleazy TV reporter who keeps hanging around, her cop boyfriend who has been arrested for dealing in drugs and stolen property, and her 19-year-old nephew who is fascinated by all things motorcycle-related.
